English title: Studies on cutting budget and yield in terms of value based on the cutting budget. I.

Abstract

An estimate of value of a forest holding is needed, for instance, when the holding is sold. There is, however, no standard method for forest valuation. This paper describes a method based on yield in terms of value that is estimated on the basis of cutting budget. The first, mensurational part of the investigation concentrates on calculation of cutting budget that can be used in forest valuation. Second part studies how chronological order of fellings changes allowable cut in forests that differ by age-class distribution and other structural properties. Structure and variation in the structure of silviculturally different forests are determined for the forests that form the data for the investigation.

According to the study, even if the forests studied in the investigation included forests which structure differed in their age-class distribution from normal forests, they could be managed in a such way that in 5-6 decades the age-class distribution resemble that of a normal forest, and have growing stock that correspond the stock of forests in Southern Finland, about 80-110 m3/ha. Based on this, the cutting budgets of the later decades of the first rotation can be assumed to be nearly even. The original age-class distribution of the forest affects, however, allowable cut of the forests during the first decade. The revenues of the first decade have small impact on the value, the later decades strong. Consequently, development of the most valuable part of the allowable cut, timber trees, has big impact on the value. The results show that in young forests the planned cut including the proportion of timber trees increases, in middle-aged forest it is relatively even, and in old forest declining. The results indicate the order of magnitude the planned cut can be in near future in diferent kinds of forests, and when different felling regimes are used to reach different goals.
